SyncRing

Precise, accurate and reliable time, phase and frequency synchronization is required in many cases for proper operation of telecommunications networks, as well as for a range of important applications that telecom networks serve: distributed computing, financial transactions, stocks and bonds trading, industrial networks, sensor reading, smart grid, billing, logging and many others.

In particular, accurate synchronization is a very important requirement to mobile network infrastructure, one of a core enablers of mobile network operation. Poor synchronization may result in handover issues, calls interruptions or drops, packets loss and user data rates degradation, while interferences and time slot misalignment will result in spectral inefficiency, poor cell edge performance and overall network capacity degradation.

On the other hand, a highly accurate phase/time synchronization between eNodeB’s reaching ±0.5-1.5μs and batter can help operators to efficiently implement advanced inter-cell coordination techniques of LTE-A including eICIC, CoMP and others, which can improve QoE, mobile network performance and spectrum utilization.

While traditional solutions based on GNSS synchronization distribution with GPS receivers at every site can provide great synchronization accuracy, its cost and complexity are becoming excessive as LTE/LTE-A networks become denser and small cells deployments accelerate. In addition, small cell deployments (number of which is growing rapidly in recent years) are often associated with indoor or dense urban deployment scenarios, where signal from GNSS satellites will often be unavailable.

The SyncRing over-the-net synchronization platform provides a cost effective integrated solution for generation and end-to-end delivery of timing/synchronization over packet-switched networks. The solution makes use of both IEEE1588v2 and Synchronous Ethernet technologies to provide robust and highly accurate synchronization solution for various applications that require precise frequency, phase and time synchronization over packet networks. Applied in Mobile Backhaul networks, the solution helps NMOs meet stringent requirements of LTE/LTE-A networks.
